It fits the Smart D220 directly, using the same connector and BMS communication protocol as the factory unit. Capacity is 3000mAh (11.4Wh), sourced to match OEM specifications.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSmart D220 fitment:\u003c\/strong\u003e\n    The Smart D220 uses a single-cell Li-Polymer pack at 3.8V nominal. The IS707 form factor — 74.60 x 53.70 x 4.70mm — occupies the full battery bay. Any deviation in thickness or connector pinout will cause BMS rejection at boot, so physical and electrical match both matter here.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through card-read, receipt print, and wireless transaction sequences. The BMS held steady through the combined current draw of the printer motor and radio stack without tripping overcurrent protection.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst deployment tip:\u003c\/strong\u003e\n    After fitting this battery, complete one full transaction cycle before putting the terminal into live service. The Smart D220 maps battery capacity during normal operation and requires at least one complete power cycle to calibrate the charge indicator correctly.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTerminal not completing PCI boot sequence after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Smart D220 runs a PCI compliance check during startup that includes a battery handshake. A new cell that hasn't completed a full charge-discharge cycle may report state-of-charge data the terminal treats as out of range. This causes the boot sequence to stall or loop before reaching the payment screen. Charge the battery to 100%, power the terminal off cleanly, then restart — one full boot-charge cycle usually clears the handshake flag.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTerminal rebooting mid-transaction during receipt printing\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe receipt printer motor draws a short burst of current well above the idle load of the display and wireless radio. On a degraded or partially discharged battery, this spike can push cell voltage below the BMS undervoltage threshold, triggering an immediate protection cutoff — which looks like a reboot. If this happens consistently, check that the cell is above 3.6V before high-volume transaction periods. A cell sitting at 3.5V under idle load will not hold voltage through a printer motor start surge.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43415923490906,"sku":"BWCS-ESD220BL-1","price":39.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43415923523674,"sku":"BWCS-ESD220BL-2","price":46.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43415923556442,"sku":"BWCS-ESD220BL-3","price":51.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ESD220BL-1.webp?v=1779757951","url":"https:\/\/batteryweb.com\/products\/eservice-smart-d220-replacement-battery-38v-3000mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
